Abstract: A hair colorant applicator in the form of a hollow comb 1 with a threaded receiver top 2 that accepts standard plastic bottles 8 of hair colorant in the inverted position. The teeth of the comb are in the form of tubes. A hollow channel 5 in each tube 3 of the comb terminates in an orifice 4a at the tip of each tube. Hair colorant 9 flows from the bottle, through the body of the comb 6, through the channels in the tubes, and exits the tips of the tubes. This applies the colorant at the base of hair near the scalp to maintain uniform hair coloring as the hair grows. Newly emerged uncolored hair near the scalp can be colored without deepening the color of the rest of the hair. The user squeezes the bottle of colorant as it is applied to control the flow rate.
